2. Description of Related Art

Liquid crystal display (LCD) panel has become the mainstream of display device for its advantages of like low radiation, low power consumption, and thinness. As such, various techniques corresponding to various demands have been developed. In particular, technique of three-dimensional (3D) image displaying is one of the devoted topics. The 3D image displaying utilizes the visual characteristic of human eyes. When two images with the same content but different parallax are separately seen by the left eye and right eye, a 3D image is sensed (viewed). In current technique of 3D image, when a display panel displays a image for left eye and image for right eye simultaneously, it is possible to let left eye (or right eye) receives both kinds of images, and it means the cross-talk phenomenon. Besides, color washout is also a general issue of a display panel in its 3D display mode, the issue would decrease the display quality of the display panel. Therefore, extra masks for forming corresponding layers, such as a mask of pixel electrode and that of black matrix, are often adopted to overcome aforementioned issues. However, it causes high cost of manufacturing a display panel.

It should be noticed is that, the connecting relation of the switch 14 of each sub-pixel and the pair of first data lines D 1 (DL 1 and DL 2 ) is shown in FIG. 1A .

Specifically, each switch 14 of each sub-pixels 161 , 162 , 163 , 181 , 182 , 183 in the first column is connected to the pair of first data lines D 1 in a zigzag manner. In FIG. 1B , for example, the data line of the pair of data lines D 1 connected to the first, second, third sub-pixel of the first sub-pixel group 16 in the first column, and the first, second, third sub-pixel of the second sub-pixel group 18 in the first column is DL 2 , DL 1 , DL 2 , DL 1 , DL 2 , DL 1 in order (from top to bottom), but the connection is not limited to it. In the connection of aforementioned switches 14 and the pair of first data lines D 1 , data line D 1 and data line D 2 are exchangeable, for example, the data line of the pair of data lines D 1 connected to the first, second, third sub-pixel of the first sub-pixel group 16 in the first column, and the first, second, third sub-pixel of the second sub-pixel group 18 in the first column can also be DL 1 , DL 2 , DL 1 , DL 2 , DL 1 , DL 2 in order (from top to bottom).

Referring to FIG. 1A and FIG. 1B together, the array substrate 10 of the present embodiment comprises at least one set of scan line GL, the set of scan line GL at least comprises a first scan line GL 1 , a second scan line GL 2 , and a third scan line GL 3 .

Wherein the gate electrode G of the switch 14 of the first sub-pixel 161 of the first sub-pixel group 16 and the gate electrode G of the switch 14 of the second sub-pixel 162 of the first sub-pixel group 16 are connected to the first scan line GL 1 ; the gate electrode G of the switch 14 of the third sub-pixel 163 of the first sub-pixel group 16 and the gate electrode G of the switch 14 of the first sub-pixel 181 of the second sub-pixel group 18 are connected to the second scan line GL 2 ; the gate electrode G of the switch 14 of the second sub-pixel 182 of the second sub-pixel group 18 and the gate electrode G of the switch 14 of the third sub-pixel 183 of the second sub-pixel group 18 is connected to the third scan line GL 3 . More specifically, each scan line GL 1 , GL 2 , and GL 3 is respectively connected to each switch of two adjacent sub-pixels which are in the same column but different rows. As shown in FIGS. 1A and 1B , the first sub-pixel group 16 and the second sub-pixel group 18 within the sub-pixel group 20 are in the same column and are corresponded to six switches 14 totally. These six switches 14 disposed respectively in six sub-pixels ( 161 , 162 , 163 , 181 , 182 , 183 ) are distributed evenly to three scan lines (GL 1 , GL 2 , GL 3 ). That is, GL 1 is connected to the gate electrodes G of the switches of sub-pixel 161 , 162 ; GL 2 is connected to the gate electrodes G of the switches of sub-pixel 163 , 181 ; GL 3 is connected to the gate electrodes G of the switches of sub-pixel 182 , 183 . It should be noticed that each sub-pixel of each sub-pixel group of the array substrate of the present disclosure has aforementioned whole new layout. With the following driving method, each sub-pixel of each sub-pixel group can be independently charged with different voltages in different time sequences, so as to let each sub-pixel of each sub-pixel group have different voltages directly. It is totally different from the prior art, which applies charge-sharing among each sub-pixel of each sub-pixel group to produce different voltages of them, the present disclosure provides a more direct and better solution to color-washout issue in wide viewing-angle than that of the related art.

FIG. 1B is top-view of part of one embodiment of the pixel layout of the array substrate of the present disclosure, the array substrate comprises the plurality of sub-pixel groups 20 , the plurality of switches 14 , pairs of first data lines D 1 (DL 1 , DL 2 ), and the plurality of scan lines GL 1 , GL 2 , GL 3 . It should be noticed is that the array substrate of the present disclosure is composed of at least two different columns with different display colors. As shown in FIG. 1B , the sub-pixel groups of the first, third columns (counted from left to right) display a first colored light; the sub-pixel groups of the second, fourth columns (counted from left to right) display a second colored light, wherein the combination of the first, second colored light could be that the first colored light is one of the three primary colors of light and the second colored light is the mixed colored light of the other two of the three primary colors of light. For example, the first colored light is red light and the second colored light is mixed colored light of green and blue, or the first colored light is mixed colored light of red and green and the second colored light is mixed colored light of green and blue, or other suitable combinations of color from CIE. As long as the combination comprises the three primary color of light (red, green, and blue), the display panel of the present disclosure is capable to display all kinds of predetermined color. To be more specific, the array substrate of the present disclosure is consisting at least two sub-pixel groups with different color in two different columns respectively. That is, the array substrate of the present disclosure can also comprises two, three, four, five, six different sub-pixel groups with different colors in different columns respectively, and the colors of each sub-pixel of the sub-pixel group in the same column are substantially the same.

For convenience of description, the following embodiments of the present invention are described in three primary color of light (red, green, and blue) in three different columns of the array substrate as examples. As shown in FIG. 2 , the sub-pixel groups of the first, fourth columns (from left to right) display the first colored light, the sub-pixel groups of the second, fifth columns (from left to right) display the second colored light, and the third, sixth columns (from left to right) display the third colored light. For example, the first colored light is red light, the second colored light is green light, and the third colored light is blue light, but not limited to it. That is the corresponding colors of the first, second, and third colored light are exchangeable, as long as the combination of the first, second, and third colored light contents three primary colors of light (red, green, and blue), the display panel of the present disclosure is capable to display all kinds of color. Besides, data line DL 1 and data line DL 2 of the pair of first data lines are exchangeable as aforementioned. That is, the connecting relation of aforementioned switches 14 and the pair of first data lines D 1 , data line D 1 and data line D 2 are exchangeable, as the array substrate 10 of the present disclosure shown in FIG. 3 , the data line of the pair of data lines D 1 connected to the first, second, third sub-pixels of the first sub-pixel group 16 in the first column, and the first, second, third sub-pixels of the second sub-pixel group 18 in the first column can also be DL 1 , DL 2 , DL 1 , DL 2 , DL 1 , DL 2 in order (from top to bottom).

Referring to FIG. 2 continually, the driving method of the array substrate of the embodiment of the present disclosure is to offering a plurality of voltages to the pair of first data lines (DL 1 , DL 2 ) in a plurality of time sequences. In the present embodiment, the pair of first data lines (DL 1 , DL 2 ) are offered three different voltages in three different time sequences respectively. Take the array substrate in FIG. 1B as an example, in the first time sequence (or namely first time clock), data line DL 1 is offered a second voltage to supply the voltage which is predetermined for the second sub-pixel 162 of the first sub-pixel group 16 , meanwhile (in the first time sequence), data line DL 2 is offered a first voltage to supply the voltage which is predetermined for the first sub-pixel 161 of the first sub-pixel group 16 ; in the second time sequence, data line DL 1 is changed to be offered a first voltage to supply the voltage which is predetermined for the first sub-pixel 181 of the second sub-pixel group 18 , meanwhile (in the second time sequence), data line DL 2 is changed to be offered a third voltage to supply the voltage which is predetermined for the third sub-pixel 163 of the first sub-pixel group 16 ; in the third time sequence, data line DL 1 is changed to be offered a third voltage to supply the voltage which is predetermined for the third sub-pixel 183 of the second sub-pixel group 18 , meanwhile (in the third time sequence), data line DL 2 is changed to be offered a second voltage to supply the voltage which is predetermined for the second sub-pixel 182 of the first sub-pixel group 18 . To be more specific, the voltages offered to data line DL 1 is changeable to supply the second, first, and third voltages in the first, second, and third time sequence respectively; and the voltages offered to data line DL 2 is also changeable to supply the first, third, and second voltages in the first, second, and third time sequence respectively. Accordingly, the voltages supplied by data line DL 1 , DL 2 in different time sequence are different from each other. In the first, second, and third time sequences, the predetermined voltages for the first, second, and third sub-pixel of the first sub-pixel group 16 and the second sub-pixel group 18 of the sub-pixel group 20 are fully charged respectively by the second, first, and third voltage supplied by data line DL 1 and the first, third, and second voltage supplied by data line DL 2 . It should be noticed that each sub-pixel of the first sub-pixel group 16 and the second sub-pixel group 18 in two adjacent rows are fully charged to having their predetermined voltages respectively then the predetermined image of them is shown while the first, second, and third time sequences are all completed. Therefore, the first, second, and third time sequences are all respectively a part of time of a frame which the frame. Referring to FIG. 1B , when the scan lines GL 1 , GL 2 , and GL 3 are turned on in aforementioned the first, second, and third time sequences respectively, each the first, second, and third sub-pixel of the first, second sub-pixel groups (such as 161 and 181, 162 and 182, and 163 and 183) is charged to have a voltage above (or namely greater than) the threshold voltage thereof respectively by switching three kinds of voltages of the data lines, DL 1 and DL 2 . The threshold voltage is the minimum voltage which forces the liquid crystal molecules in each sub-pixel to rotate and to start having optical transmittance. When a sub-pixel substantially has a voltage greater than its threshold voltage, the higher the voltage is, the greater the optical transmittance of the sub-pixel is. The voltage is proportional to the optical transmittance until the optical transmittance of the sub-pixel reaches its maximum, and the voltage of it is called the saturated voltage. It should be noticed that the first voltage, the second voltage, and the third voltage are different from each other. When the array substrate of the display panel of one embodiment of the present disclosure is in its 2D mode (or namely two dimension display mode), the first, second, and the third sub-pixel of the first sub-pixel group and the second sub-pixel group are having different voltages respectively. That is, the voltages of the first sub-pixel 161 , the second sub-pixel 162 , and the third sub-pixel 163 are different from each other; and the voltages of the first sub-pixel 181 , the second sub-pixel 182 , and the third sub-pixel 183 are also different from each other. The first voltage, the second voltage, and the third voltage are all substantially greater than the threshold voltages of each sub-pixels. To be more specific, each sub-pixel of each sub-pixel group has a voltage which is greater than its threshold voltage, and therefore each sub-pixel has a optical transmittance. The sub-pixels have different voltages, and the degrees of their optical transmittance are also different. It results in that the sub-pixels display different intensity of light from each other.

Furthermore, in one embodiment of the present disclosure, when the array substrate of the display panel is in 2D mode, except all sub-pixels of all sub-pixel groups have voltages above (or namely greater than) their threshold voltages, the first voltage is substantially greater than the second voltage, and the second voltage is substantially greater than the third voltages. Therefore, when the array substrate of the display panel of the present disclosure is in 2D mode, the voltages of the first sub-pixel ( 161 , 181 ) are substantially greater than those of the second sub-pixel ( 162 , 182 ) and the voltages of the second sub-pixel ( 162 , 182 ) are substantially greater than those of the third sub-pixel ( 163 , 183 ). That is, the voltage of the first sub-pixel 161 is substantially greater than that of the second sub-pixel 162 , and the voltage of the second sub-pixel 162 is substantially greater than that of the third sub-pixel 163 ; the voltage of the first sub-pixel 181 is substantially greater than that of the second sub-pixel 182 , and the voltage of the second sub-pixel 182 is substantially greater than that of the third sub-pixel 183 . Therefore, all sub-pixels of the display panel have different optical transmittances. In each sub-pixel group, the brightness of the first sub-pixel is the highest, that of the second sub-pixel is secondary, and that of the third sub-pixel is the lowest. When aforementioned sub-pixel groups are all enabled, all sub-pixels of the first sub-pixel group 16 display the same color of light, and so do all sub-pixels of the second sub-pixel group 18 . Preferably, the first sub-pixel group 16 and the second sub-pixel group 18 display the same color of light.

Referring to FIG. 4 , in one embodiment of the present disclosure, when the array substrate of the display panel is in 3D mode (or namely stereographic display mode, three dimension display mode), there are black regions (or namely light shading region) 40 between the sub-pixels for left eye and right eye of the observer to separate the images displayed, and to avoid the issue of cross-talk. The issue of cross-talk occurs when the right eye observes the wrong images, which are predetermined for the left eye, vice versa. As shown in FIG. 4 , when the array substrate 10 of the display panel is in 3D display mode, just allow the first voltage offered by the pair of first data lines D 1 (DL 1 , DL 2 ) in each time sequence substantially to be less than the threshold voltages of the first sub-pixels of each sub-pixel group according to aforementioned driving method. So as the first sub-pixels 161 , 181 are not enabled (or namely disabled) in each time sequence and become the black regions 40 respectively. Meanwhile, the second voltage is still substantially greater than the threshold voltages of the second sub-pixels 162 , 182 , and the third voltage is still substantially greater than the threshold voltages of the third sub-pixels 163 , 183 . That is, the second sub-pixels ( 162 , 182 ) and the third sub-pixels ( 163 , 183 ) are enabled and having optical transmittances. Referring to FIG. 4 , in one embodiment of the present disclosure, the second sub-pixel 162 of the first sub-pixel group 16 and the third sub-pixel 163 of the first sub-pixel group 16 offer the display images (L 1 , L 2 ) for left eye of observers, and the second sub-pixel 182 of the second sub-pixel group 18 and the third sub-pixel 183 of the second sub-pixel group 18 offer the display images (R 1 , R 2 ) for right eye of observers. The first sub-pixel 161 of the first sub-pixel group 16 and the first sub-pixel 181 of the second sub-pixel group 18 are opaque and become the black regions 40 to separate the images from the sub-pixels which are predetermined to offer the images for right eye and left eye respectively since the first sub-pixel 161 of the first sub-pixel group 16 and the first sub-pixel 181 of the second sub-pixel group 18 are having voltages which are lower than their threshold voltages. So the issue of cross-talk is avoided and the display quality in 3D mode of the array substrate of the display panel of the present disclosure is improved.

Referring to FIG. 5 , in one embodiment of the present disclosure, the array substrate of the display panel has wider black regions 40 to avoid aforementioned issue of cross-talk which could happened in 3D mode observed by wider view angles. As shown in FIG. 5 , when the array substrate 10 of the display panel is in 3D display mode, just allow the third voltage and the first voltage offered by the pair of first data lines D 1 (DL 1 , DL 2 ) in the second time sequence substantially to be less than the threshold voltages of the third sub-pixel 163 of the first sub-pixel group 16 and the first sub-pixel 181 of the second sub-pixel group 18 according to aforementioned driving method. So as the third sub-pixel 163 of the first sub-pixel group 16 and the first sub-pixel 181 of the second sub-pixel group 18 are not enabled in each time sequence (since the second time sequence is the only chance for them to be charged) and become the black regions 40 respectively. Meanwhile, the second voltage and the first voltage offered by the pair of first data lines D 1 (DL 1 , DL 2 ) in the first time sequence are substantially greater than the threshold voltages of the second sub-pixel 162 of the first sub-pixel group 16 and the first sub-pixel 161 of the first sub-pixel group 16 ; the third voltage and the second voltage offered by the pair of first data lines D 1 (DL 1 , DL 2 ) in the third time sequence are substantially greater than the threshold voltages of the third sub-pixel 183 of the second sub-pixel group 18 and the second sub-pixel 182 of the second sub-pixel group 18 . As shown in FIG. 5 , the first sub-pixel 161 and the second sub-pixel 162 of the first sub-pixel groups 16 display the images L 1 which is predetermined for left eye of the observer; and the second sub-pixel 182 and the third sub-pixel 183 of the second sub-pixel groups 18 display the images R 1 which is predetermined for right eye of the observer. The third sub-pixel 163 of the first sub-pixel group 16 and the first sub-pixel 181 of the second sub-pixel group 18 are opaque as black regions 40 because of having the voltages which are substantially less than their threshold voltages respectively. Accordingly, the embodiment of the present disclosure shown in FIG. 5 has wider black regions 40 than those of the embodiment of the present disclosure shown in FIG. 4 . That is, the issue of cross-talk can be avoid even when the array substrate of the display panel is in 3D mode and being observed in wider view angles. Therefore, a better quality of 3D images can be achieved.

In other embodiments of the present disclosure, DL 1 and DL 2 can be disposed in the same side of the first sub-pixel group 16 and the second sub-pixel group 18 . Therefore, the first sub-pixel group 16 and the second sub-pixel group 18 are arranged along with the extending direction of the pair of first data lines D 1 (DL 1 and DL 2 ). The connection of the switch 14 of each sub-pixel the first sub-pixel group 16 and the second sub-pixel group 18 and the pair of first data lines D 1 (DL 1 and DL 2 ) is similar to that shown in FIG. 1A . The data line DL 1 of the pair of first data lines D 1 is connected to the switches 14 of the second sub-pixel 162 of the first sub-pixel group 16 , the first sub-pixel 181 of the second sub-pixel group 18 , third sub-pixel 183 of the second sub-pixel group 18 , while DL 2 of the pair of first data lines D 1 is connected to the switches 14 of the first sub-pixel 161 of the first sub-pixel group 16 , the third sub-pixel 163 of the first sub-pixel group 16 , and the second sub-pixel 182 of the second sub-pixel group 18 , but not limited to it. Specifically, each switch 14 of each sub-pixel in the first column is connected to the pair of first data lines D 1 (DL 1 , DL 2 ) in a zigzag manner. In FIG. 6A , for example, the data line of the pair of first data lines D 1 connected to the first, second, third sub-pixels of the first sub-pixel group 16 in the first column, and the first, second, third sub-pixels of the second sub-pixel group 18 in the first column is DL 2 , DL 1 , DL 2 , DL 1 , DL 2 , DL 1 in order (from top to bottom), but the connection is not limited to it.

Referring to FIG. 6A , each switch 14 of each sub-pixel of the third sub-pixel group 26 and the fourth sub-pixel group 28 is electrically connected to the pair of second data lines D 2 (DL 3 and DL 4 ). The pair of second data lines D 2 (DL 3 and DL 4 ) can be disposed in two sides of the third sub-pixel group 26 and the fourth sub-pixel group 28 preferably, that is, the third sub-pixel group 26 and the fourth sub-pixel group 28 are disposed in the second column which is defined by the pair of second data lines D 2 (DL 3 and DL 4 ) as shown in FIG. 6A , but not limited to it. Wherein, the second column and the first column is different each other. In other embodiments of the present disclosure, DL 1 and DL 2 can be disposed in the same side of the third sub-pixel group 26 and the fourth sub-pixel group 28 . Therefore, the third sub-pixel group 26 and the fourth sub-pixel group 28 are arranged along with the extending direction of the pair of second data lines DL 3 and DL 4 . It should be noticed that, the connecting relation between each switch 14 in the second column and the pair of second data lines D 2 (DL 3 , DL 4 ) is mirror symmetry to those between each switch 14 in the first column and the pair of first data lines D 1 (DL 1 , DL 2 ) based on the boundary of the first column and the second column. More specifically, the connection of the switch 14 of each sub-pixel the first sub-pixel group 16 and the second sub-pixel group 18 in the first column is that DL 1 of the pair of first data lines D 1 is connected to the switches 14 of the second sub-pixel 162 of the first sub-pixel group 16 , the first sub-pixel 181 of the second sub-pixel group 18 , third sub-pixel 183 of the second sub-pixel group 18 ; DL 2 of the pair of first data lines D 1 is connected to the switches 14 of the first sub-pixel 161 of the first sub-pixel group 16 , the third sub-pixel 163 of the first sub-pixel group 16 , and the second sub-pixel 182 of the second sub-pixel group 18 , while the connecting relation of the switch 14 of each sub-pixel the third sub-pixel group 26 and the fourth sub-pixel group 28 in the second column is that DL 3 of the pair of second data lines D 2 is connected to the switches 14 of the first sub-pixel 261 of the third sub-pixel group 26 , the third sub-pixel 263 of the third sub-pixel group 26 , and the second sub-pixel 282 of the fourth sub-pixel group 28 ; DL 4 of the pair of second data lines D 2 is connected to the switches 14 of the second sub-pixel 262 of the third sub-pixel group 26 , the first sub-pixel 281 of the fourth sub-pixel group 28 , the third sub-pixel 283 of the fourth sub-pixel group 28 . Specifically, each switch 14 of each sub-pixel in the first column is connected to the pair of first data lines D 1 (DL 1 , DL 2 ) in a zigzag manner; and each switch 14 of each sub-pixel in the second column is connected to the pair of second data lines D 2 (DL 1 , DL 2 ) in the other zigzag manner. These two zigzag manners are also in a staggered relationship to each other, and mirror symmetry by the symmetry axis (the boundary between the first column and the second column) is formed. In FIG. 6A , for example, the data line of the pair of first data lines D 1 connected to the first, second, third sub-pixels of the first sub-pixel group 16 in the first column, and the first, second, third sub-pixels of the second sub-pixel group 18 in the first column is DL 2 , DL 1 , DL 2 , DL 1 , DL 2 , DL 1 in order (from top to bottom) while the data line of the pair of second data lines D 2 connected to the first, second, third sub-pixels of the third sub-pixel group 26 in the second column, and the first, second, third sub-pixels of the fourth sub-pixel group 28 in the second column is DL 3 , DL 4 , DL 3 , DL 4 , DL 3 , DL 4 in order (from top to bottom), but not limited to it. In the connection of aforementioned switches 14 and the pair of first data lines D 1 , data line D 1 and data line D 2 are exchangeable. However, if data line D 1 and data line D 2 are exchanged, data line D 3 and data line D 4 must be also exchanged. For example, if the data line of the pair of first data lines D 1 connected to the first, second, third sub-pixels of the first sub-pixel group 16 in the first column, and the first, second, third sub-pixels of the second sub-pixel group 18 in the first column is exchanged to be DL 1 , DL 2 , DL 1 , DL 2 , DL 1 , DL 2 in order (from top to bottom), the data line of the pair of second data lines D 2 connected to the first, second, third sub-pixels of the first sub-pixel group 16 in the first column, and the first, second, third sub-pixels of the second sub-pixel group 18 in the first column must be exchanged to be DL 4 , DL 3 , DL 4 , DL 3 , DL 4 , DL 3 in order (from top to bottom) correspondingly.

All scan lines of the set of scan line GL are crossed to (or namely interlaced to) the pair of first data lines D 1 (DL 1 , DL 2 ) and the pair of second data lines D 2 (DL 3 , DL 4 ).

More specifically, each scan line GL 1 , GL 2 , and GL 3 is respectively connected to each switch of two adjacent sub-pixels which are in the same column but different rows. As shown in FIG. 6A , the sub-pixel group 20 has the first sub-pixel group 16 and the second sub-pixel group 18 in the first column, the third sub-pixel group 26 and the fourth sub-pixel group 28 second column, and are corresponded to twelve switches 14 totally. These twelve switches 14 disposed respectively in twelve sub-pixels ( 161 , 162 , 163 , 181 , 182 , 183 , 261 , 262 , 263 , 281 , 282 , 283 ) are distributed evenly to three scan lines (GL 1 , GL 2 , GL 3 ). That is, GL 1 is connected to the gate electrodes G of the switches of sub-pixel 161 , 162 , 261 and 262 ; GL 2 is connected to the gate electrodes G of the switches of sub-pixel 163 , 181 , 263 and 281 ; GL 3 is connected to the gate electrodes G of the switches of sub-pixel 182 , 183 , 282 and 283 .

Besides, three primary color of light disposed in three different columns respectively is the example as describing the present embodiment. FIG. 6B is top-view of part of one embodiment of the pixel layout of the array substrate of the present disclosure. As shown in FIG. 6B , the sub-pixel groups of the first, fourth columns (counted from left to right) display a first colored light; the sub-pixel groups of the second, fifth columns (counted from left to right) display a second colored light; the sub-pixel groups of the third, sixth columns (counted from left to right) display a third colored light, wherein the first colored light could be red light, the second colored light could be green light, and the third colored light could be blue light, but not limited to it. That is, the first, second and third colored light are exchangeable, as long as the combination of them includes three primary color of light (red, green, and blue), the display panel of the present disclosure is capable to display all kinds of predetermined color. In addition, the array substrate of the present disclosure is also as aforementioned embodiments, consisting two different colors in two different columns respectively, or consisting four, five, six different colors in four, five, six different columns respectively. That is, the array substrate of the present disclosure can also comprises two, three, four, five, six different sub-pixel groups with different colors in different columns respectively, and the colors of each sub-pixel of the sub-pixel group in the same column are substantially the same.

Referring to FIG. 6B , the driving method of the array substrate of another embodiment of the present disclosure is to offering a plurality of voltages to the pair of first data lines D 1 (DL 1 , DL 2 ) and the pair of second data lines D 2 (DL 3 , DL 4 ) in a plurality of time sequences. Specifically, in the present embodiment, the pair of first data lines D 1 (DL 1 , DL 2 ) and the pair of second data lines D 2 (DL 3 , DL 4 ) are offered three different voltages in three different time sequences (or namely three different time clock) respectively. The three different voltages offered to the pair of second data lines D 2 (DL 3 , DL 4 ) could be the same with or different from the three different voltages offered to the pair of first data lines D 1 (DL 1 , DL 2 ). To describe clearly, the three different voltages offered to the pair of second data lines D 2 (DL 3 , DL 4 ) are the same with the three corresponding voltages offered to the pair of first data lines D 1 (DL 1 , DL 2 ) as an example, and the present embodiment is described as shown in FIG. 6B . In the first time sequence, data line DL 1 is offered a second voltage to supply the voltage which is predetermined for the second sub-pixel 162 of the first sub-pixel group 16 , data line DL 2 is offered a first voltage to supply the voltage which is predetermined for the first sub-pixel 161 of the first sub-pixel group 16 , data line DL 3 is offered a first voltage to supply the voltage which is predetermined for the first sub-pixel 261 of the third sub-pixel group 26 , and data line DL 4 is offered a second voltage to supply the voltage which is predetermined for the second sub-pixel 262 of the third sub-pixel group 26 ; in the second time sequence, data line DL 1 is changed to be offered a first voltage to supply the voltage which is predetermined for the first sub-pixel 181 of the second sub-pixel group 18 , data line DL 2 is changed to be offered a third voltage to supply the voltage which is predetermined for the third sub-pixel 163 of the first sub-pixel group 16 , data line DL 3 is changed to be offered the third voltage to supply the voltage which is predetermined for the third sub-pixel 263 of the third sub-pixel group 26 , data line DL 4 is changed to be offered the first voltage to supply the voltage which is predetermined for the first sub-pixel 281 of the fourth sub-pixel group 28 ; in the third time sequence, data line DL 1 is changed to be offered a third voltage to supply the voltage which is predetermined for the third sub-pixel 183 of the second sub-pixel group 18 , data line DL 2 is changed to be offered the second voltage to supply the voltage which is predetermined for the second sub-pixel 182 of the second sub-pixel group 18 , data line DL 3 is changed to be offered the second voltage to supply the voltage which is predetermined for the second sub-pixel 282 of the fourth sub-pixel group 28 , and data line DL 4 is changed to be offered the third voltage to supply the voltage which is predetermined for the third sub-pixel 283 of the fourth sub-pixel group 28 . To be more specific, the voltages offered to data line DL 1 is changeable to supply the second, first, and third voltages in the first, second, and third time sequences respectively; the voltages offered to data line DL 2 is changeable to supply the first, third, and second voltages in the first, second, and third time sequences respectively; the voltages offered to data line DL 3 is changeable to supply the first, third, and second voltages in the first, second, and third time sequences respectively; and the voltages offered to data line DL 4 is changeable to supply the second, first, and third voltages in the first, second, and third time sequences respectively. Accordingly, the voltages supplied by data line DL 1 , DL 2 in different time sequence are different from each other, and the voltages supplied by data line DL 3 , DL 4 in different time sequence are also different from each other. In the first, second, and third time sequences, the predetermined voltages for the first, second, and third sub-pixel of the first sub-pixel group 16 and the second sub-pixel group 18 of the sub-pixel group 20 are fully charged respectively by the second, first, and third voltage supplied by data line DL 1 and the first, third, and second voltage supplied by data line DL 2 ; and the predetermined voltages for the first, second, and third sub-pixel of the third sub-pixel group 26 and the fourth sub-pixel group 28 of the sub-pixel group 20 are fully charged respectively by the first, third, and second voltage supplied by data line DL 3 and the second, first, and third voltage supplied by data line DL 4 . It should be noticed that each sub-pixel of the first sub-pixel group 16 and the second sub-pixel group 18 , the third sub-pixel group 26 and the fourth sub-pixel group 28 in two adjacent rows are fully charged to having their predetermined voltages respectively then the predetermined image of them is shown while the first, second, and third time sequences are all completed. Therefore, the first, second, and third time sequences are all respectively a part of time of a frame which the frame. Referring to FIG. 6B , when the scan lines GL 1 , GL 2 , and GL 3 are turned on in aforementioned the first, second, and third time sequences respectively, each the first, second, and third sub-pixel of the first, second, third, and fourth sub-pixel group is charged to have a voltage above the threshold voltage thereof respectively by switching three kinds of voltages of the data lines, DL 1 , DL 2 , DL 3 , and DL 4 . The threshold voltage is the minimum voltage which forces the liquid crystal molecules in each sub-pixel to rotate and to start having optical transmittance. When a sub-pixel substantially has a voltage substantially greater than its threshold voltage, the higher the voltage is, the greater the optical transmittance of the sub-pixel is. The voltage is proportional to the optical transmittance until the optical transmittance of the sub-pixel reaches its maximum, and the voltage of it is called the saturated voltage. It should be noticed that the first voltage, the second voltage, and the third voltage are different from each other. When the array substrate of the display panel of one embodiment of the present disclosure is in its 2D mode, the first, second, and the third sub-pixel of the first sub-pixel group and the second sub-pixel group are having different voltages respectively. That is, the voltages of the first sub-pixel 161 , the second sub-pixel 162 , and the third sub-pixel 163 in first sub-pixel group 16 are different from each other; and the voltages of the first sub-pixel 181 , the second sub-pixel 182 , and the third sub-pixel 183 in second sub-pixel group 18 are different from each other; the voltages of the first sub-pixel 261 , the second sub-pixel 262 , and the third sub-pixel 263 in third sub-pixel group 26 are different from each other; the voltages of the first sub-pixel 281 , the second sub-pixel 282 , and the third sub-pixel 283 in fourth sub-pixel group 28 are also different from each other. The first voltage, the second voltage, and the third voltage are all substantially greater than the threshold voltages of each sub-pixel. To be more specific, each sub-pixel of each sub-pixel group has a voltage which is substantially greater than its threshold voltage, and therefore each sub-pixel has an optical transmittance. The sub-pixels have different voltages, and the degrees of their optical transmittance are also different. It results in that the sub-pixels display different intensity of light from each other.

Referring to FIG. 6B , furthermore, in one embodiment of the present disclosure, when the array substrate of the display panel is in 2D mode, except all sub-pixels of all sub-pixel groups have voltages above (or namely substantially greater than) their threshold voltages, the first voltage is substantially greater than the second voltage, and the second voltage is substantially greater than the third voltages. Therefore, when the array substrate of the display panel of the present disclosure is in 2D mode, the voltages of the first sub-pixel ( 161 , 181 , 261 , 281 ) are substantially greater than those of the second sub-pixel ( 162 , 182 , 262 , 282 ) and the voltages of the second sub-pixel ( 162 , 182 , 262 , 282 ) are substantially greater than those of the third sub-pixel ( 163 , 183 , 263 , 283 ). Therefore, all sub-pixels of the display panel have different optical transmittances. In each sub-pixel group, the brightness of the first sub-pixel is the highest, that of the second sub-pixel is secondary, and that of the third sub-pixel is the lowest. When aforementioned sub-pixel groups are all enabled, all sub-pixels of the first sub-pixel group 16 display the same color of light; all sub-pixels of the second sub-pixel group 18 display the same color of light; all sub-pixels of the third sub-pixel group 26 display the same color of light; and all sub-pixels of the fourth sub-pixel group 28 display the same color of light. Preferably, the first sub-pixel group 16 and the second sub-pixel group 18 display substantially the same color of light, and the third sub-pixel group 26 and the fourth sub-pixel group 28 display substantially the same color of light.

Referring to FIG. 8 , in another embodiment of the present disclosure, when the array substrate of the display panel is in 3D mode, there are black regions (or namely light shading region) 40 between the sub-pixels for left eye and right eye of the observer to separate the images displayed, and to avoid the issue of cross-talk. The issue of cross-talk occurs when the right eye observes the wrong images, which are predetermined for the left eye, vice versa. As shown in FIG. 8 , when the array substrate 10 of the display panel is in 3D display mode, just allow the first voltage offered by the pair of first data lines D 1 (DL 1 , DL 2 ) and the pair of second data lines D 2 (DL 3 , DL 4 ) in each time sequence substantially to be less than the threshold voltages of the first sub-pixels of each sub-pixel group according to aforementioned driving method. So as the first sub-pixels 161 , 181 , 261 , 281 are not enabled (or namely disabled) in each time sequence and become the black regions 40 respectively. Meanwhile, the second voltage is still substantially greater than the threshold voltages of the second sub-pixels 162 , 182 , 262 , 282 and the third voltage is still substantially greater than the threshold voltages of the third sub-pixels 163 , 183 , 263 , 283 . That is, the second sub-pixels ( 162 , 182 , 262 , 282 ) and the third sub-pixels ( 163 , 183 , 263 , 283 ) are enabled and having optical transmittances. Referring to FIG. 8 , the second sub-pixel 162 of the first sub-pixel group 16 , the third sub-pixel 163 of the first sub-pixel group 16 , the second sub-pixel 262 of the third sub-pixel group 26 , and the third sub-pixel 263 of the third sub-pixel group 26 offer the display images (L 1 , L 2 ) for left eye of observers, and the second sub-pixel 182 of the second sub-pixel group 18 , the third sub-pixel 183 of the second sub-pixel group 18 , the second sub-pixel 282 of the fourth sub-pixel group 28 , and the third sub-pixel 283 of the fourth sub-pixel group 28 offer the display images (R 1 , R 2 ) for right eye of observers. The first sub-pixel 161 of the first sub-pixel group 16 , the first sub-pixel 181 of the second sub-pixel group 18 , the first sub-pixel 261 of the third sub-pixel group 26 , and the first sub-pixel 281 of the fourth sub-pixel group 28 are opaque and become the black regions 40 to separate the images from the sub-pixels which are predetermined to offer the images for right eye and left eye respectively since the first sub-pixel 161 of the first sub-pixel group 16 , the first sub-pixel 181 of the second sub-pixel group 18 , the first sub-pixel 261 of the third sub-pixel group 26 , and the first sub-pixel 281 of the fourth sub-pixel group 28 are having voltages which are substantially lower than their threshold voltages. So the issue of cross-talk is avoided and the display quality in 3D mode of the array substrate of the display panel of the present disclosure is improved.

Referring to FIG. 9 , in one embodiment of the present disclosure, the array substrate of the display panel has wider blackout areas 40 to avoid aforementioned issue of cross-talk which could happened in 3D mode observed by wider view angles. As shown in FIG. 9 , when the array substrate 10 of the display panel is in 3D display mode, just allow the third voltage and the first voltage offered by the pair of first data lines D 1 (DL 1 , DL 2 ) and the pair of second data lines D 2 (DL 3 , DL 4 ) in the second time sequence substantially to be less than the threshold voltages of the third sub-pixel 163 of the first sub-pixel group 16 , the first sub-pixel 181 of the second sub-pixel group 18 , the third sub-pixel 263 of the third sub-pixel group 26 , and the first sub-pixel 281 of the fourth sub-pixel group 28 according to aforementioned driving method. So as the third sub-pixel 163 of the first sub-pixel group 16 , the first sub-pixel 181 of the second sub-pixel group 18 , the third sub-pixel 263 of the third sub-pixel group 26 , and the first sub-pixel 281 of the fourth sub-pixel group 28 are not enabled in each time sequence (since the second time sequence is the only chance for them to be charged) and become the black regions 40 respectively. Meanwhile, the second voltage and the first voltage offered by the pair of first data lines D 1 (DL 1 , DL 2 ) and the pair of second data lines D 2 (DL 3 , DL 4 ) in the first time sequence are substantially greater than the threshold voltages of the second sub-pixel 162 of the first sub-pixel group 16 , the first sub-pixel 161 of the first sub-pixel group 16 , the second sub-pixel 262 of the third sub-pixel group 26 , the first sub-pixel 261 of the third sub-pixel group 26 ; the third voltage and the second voltage offered by the pair of first data lines D 1 (DL 1 , DL 2 ) and the pair of second data lines D 2 (DL 3 , DL 4 ) in the third time sequence are substantially greater than the threshold voltages of the third sub-pixel 183 of the second sub-pixel group 18 , the second sub-pixel 182 of the second sub-pixel group 18 , the third sub-pixel 283 of the fourth sub-pixel group 28 , and the second sub-pixel 282 of the fourth sub-pixel group 28 . As shown in FIG. 9 , the first sub-pixel 161 of the first sub-pixel group 16 , the second sub-pixel 162 of the first sub-pixel group 16 , the first sub-pixel 261 of the third sub-pixel group 26 , and the second sub-pixel 262 of the third sub-pixel group 26 display the images L 1 which is predetermined for left eye of the observer. The second sub-pixel 182 of the second sub-pixel group 18 , the third sub-pixel 183 of the second sub-pixel group 18 , the second sub-pixel 282 of the second sub-pixel group 28 , and the third sub-pixel 283 of the second sub-pixel group 28 display the images R 1 which is predetermined for right eye of the observer. The third sub-pixel 163 of the first sub-pixel group 16 , the first sub-pixel 181 of the second sub-pixel group 18 , the third sub-pixel 263 of the third sub-pixel group 26 , and the first sub-pixel 281 of the fourth sub-pixel group 28 are opaque as black regions 40 because of having the voltages which are substantially less than their threshold voltages respectively. Accordingly, the embodiment of the present disclosure shown in FIG. 9 has wider black regions 40 than those of the embodiment of the present disclosure shown in FIG. 8 . That is, the issue of cross-talk can be avoid even when the array substrate of the display panel is in 3D mode and being observed in wider view angles. Therefore, a better quality of 3D images can be achieved.

It should be noticed that the array substrate of the display panel of the present disclosure has a whole new design of pixel layout. The masks for 2D display mode are also the masks for 3D display mode of the display panel so as to reduce the cost of manufacturing. Furthermore, the color washout issue of 3D display mode in wider viewing angle is also improved by independently controlling each sub-pixels of the array substrate with the whole new design of pixel layout.
